Patented Sept. 22, 1951 UNITED] STATES FREDERICK M. VENZIE, OF PHILADELPHIA, PENNSYLVANIA PLASTER BOAR-D BUILDING- CONSTRUCTJiON Application filed May 6,

This invention, stated in its broadest terms, relates to a building construction and has more especial relation to a building construction for interior use in which plaster blocks 5 or tiles are employed, such as are usually tinted or colored to correspond with interior decorations. As now generally practiced in the builders trade, it is customary to have bricklayers erect a wall, whereupon plasterers Thereafter the bricklayers apply the plaster blocks ortiles in accordance with certainrules and regulations prescribed by the labor unions. According to the same set of rules or regulations of the unions where, instead of bricklayers erecting walls or partitions to receive the plaster blocks or tiles, lathers erect lathing to accept plaster for ceiling constructions, it is required that the lathers erect the plaster blocks or tiles. By these rules and regulations 21 slowing-up of time for erection and an unnecessary expense is entailed, placing an undue hardship or burden upon the centractor and owner of the building being 25 erected.

The leading object of the present invention may besaid toreside in the provision of a system of plaster block or tile erection whereby the above recited disadvantages may be overcome and plastering eliminated, thereby quickening the job and reducing erecting costs. a

A further object of the present invention is to provide a system of plaster block or tile erection in'which combined plaster boards and plaster blocks are employed in which, if

desired, the blocks or tiles may becolored, tinted, or otherwise decorated prior to erection.

A still further object 'of the-present inven- 1930. Serial No. 450,098.

attached to plaster boards before erection and which plaster boards are arranged and constructed to be readily secured together by means of special clips in a few minutes time.

Other and further objects of the present invention reside in the provision of general details of construction and in the arrangement, connection, andcombination of parts for attaining the results sought by the foreor tiles clipped with respect to one another, said figure being viewed in rear elevatlon' from the lower portion of Fig 1;

' Fig. 3 is' a fragmentary view 1n sectlon illustrating combined plaster boards and plaster blocksor tiles arranged for erection; Fig. 4 is a view in perspective of a clip as employed in connecting a plaster block to my plaster board I Fig.5 is a similar view'of a clip for coupling together adjacent plaster boards; Fig. 6 is a similar view of a clip for secur "ing my combined plaster board and plaster block or tile to a vertical channel; and

Fig. 7 is a similar view of a clip for securing my combined plaster board and plaster block or tile to a channel adjacent the floor line.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring now to the drawings in detail, and with especial relation to Fig. 1:, the reference numeral 10 designates a vertical channel and the reference numeral 11 designates a horizontal channel, such as are employed in conventional building construction, channel 11 being suspended from a channel iron 12 by means of a strap or hanger 13. To these channels I attach. my improved plaster board and plaster block or tile which is seen in Fig. 3. The plaster board may be of conventional type comprising a plaster like body 14 enveloped in a paper covering 15, although I have in mind employing any of the plaster boards disclosed in my copending applications for Letters Patent, Serial No, 425,151, filed February 1, 1930; Serial No. 427,773, filed Februar 12, 1930; and Serial No. 447,586, filed pril 26, 1930.

The plaster block, slab, or tile is designated by reference numeral 16 and is usually of fireproofing material and is preferably possessed of sound-deadening characteristics, although any desired construction of plaster block or slab may be employed. The plaster block or slab 16 is adhesively secured to a plaster board as by cementing the central part thereof. as at 17, see Fig. 3, so that a marginal open space 18 is present between the adjacent faces of the plaster board and plaster block so that clips hereinafter to be described may be employed. There is thus left upon the plaster block or slab a marginal portion or ledge with a space between adjacent edges of the plaster boards, as is clearly illustrated in Fig. 3. The plaster blocks or slabs-16 may, if desired, be colored or tinted before the plaster boards are erected. Referring now to Fig. 1, the lowermost plaster board adjacent the floor 19 is secured with respect to the vertical channel 10 by means of aclip, best seen in- Fig. 7 This clip comprises an integral structure stamped from sheet metaland provided with a relatively fiat body 20 adapted to-rest upon the floor. 19 and having upturned parts 21 and 22 of whichthe part 22 is pointed to engage a space betweenthe plaster board slab and the part 21 is adapted to bebent around the channel 10 to clamp the plaster board and its slab to the channel 10, it being understood that the plaster board rests upon the upper surface of the body 20. The plaster boards are clamped to the ver-.

tical channeLlO intermediate its height by means of the clips, best seen in Fig. 6. Each clip consists of a body 23 which is relatively fiat and has a part '24 which is bent around the channel 10 to clamp the combined plaster board and slab to place, and is provided with a pointed part 25 to engage a space'18 between a plaster board and slab, see Fig. 1. The

plaster boards rest upon the body 23 of the clip between fingers 26 and 27, the fingers 27 being pointed to engage a space 18 between a plaster board and slab, see Fig. 1.

Referring now to Fig. 5 there is disclosed a clip comprising a body portion 28 which has formed integrally therewith fingers 29 and 30, the fingers 30 being pointed to engage a space 18 between a plaster board and slab, see the-upper central portion of Fig. 1. This clip is used for coupling together the horizontally disposed plaster boards as usedin forming a ceiling structure.

Referring now to Fig. 4, there is disclosed a clip having a flat body portion 31 projected from which are fingers 32 and 33, the fingers .33 being pointed to engage a space 18 between a plaster board and slab, see the right hand side of Fig. 1 and the upper portion there-of. These clips are used at the ends of the plaster boards which are not coupled with another plaster board.

All of the clips shown in Figs; 4to 7 inclusive are stamped from a single sheet of metal and are very cheaply manufactured and form convenient means for attaching together plaster boards with slabs or blocks secured thereto. In practice these various clip-s are hidden from view. With the plaster boards and their slabs in assembled position as shown in Fig. 1, the space 18 between a plaster board and slab is filled in with plaster or cement designated by the reference numeral 34 in Fig.2. Thus, the clips and cement or plaster 34 securely hold together the various plaster boards and their slabs.

In practice the various fingers of the clipstion a precast slab which slab is secured centrally of the plaster board so as to leave a marginal unattached portion of said slab, and means including clips for coupling together a plurality of said articles in erected position.

In testimony whereof, I have hereunto signed my name.
